ABSTRACT

This review focuses on issues of anticoagulant therapy in patients with atrial fibrillation (AF) associated with chronic kidney disease (CKD). Such patients are at high risk of stroke whereas the choice of an anticoagulant is difficult. A wealth of information about a negative effect of warfarin on the kidney function has accumulated. A need for an alternative therapy to warfarin for patients with stage 3-4 CKD has become imminent. In this regard, rivaroxaban seems to be an appropriate replacement for warfarin in such patients. In randomized, controlled studies that evaluated the efficacy of direct oral anticoagulants in comparison with warfarin, the efficacy and safety profile of a "kidney" dose in moderate disorders of kidney function has been studied only for rivaroxaban. Moreover, both randomized, controlled studies and studies performed in the conditions of clinical practice, have demonstrated a more favorable effect of rivaroxaban on kidney function compared to warfarin. Patients with AF associated with CKD require a comprehensive protection, which, according to results of clinical studies, may be provided by rivaroxaban.

ABSTRACT

Aim To evaluate frequency of administration of anticoagulant therapy (ACT) for atrial fibrillation and to study the effect of chronic antithrombotic therapy (ATT) on kidney function.Material and methods Due to a high medical and social significance of AF, much attention is presently paid to appropriate administration of ACT for AF in clinical practice. The study retrospectively analyzed 776 case reports of hospitalized patients with AF. The effect of chronic ATT on kidney function was studied in 70 patients who were rehospitalized, including 25 patients treated with warfarin, 25 patients treated with direct oral anticoagulants (DOAC), and 20 patients treated with acetylsalicylic acid (ASA).Results In January 2014, at the prehospital stage, 74.3 % of patients did not receive ATT, 14.7 % of patients received antiplatelet therapy, and only 11 % received anticoagulants. In the hospital in January 2014, ACTs were administered to 74.3 % of patients (warfarin, 58.6 %; DOAC, 15.7 %), 20.6 % of patients received antiplatelet drugs, and 5.1 % of patients were discharged without ATT. In January 2019, the number of patients receiving ACT at the prehospital stage increased to 58.1 % (warfarin, 13.8 %; DOAC, 44.3 %); 12 % of patients received antiplatelet drugs; and 29.9 % of patients did not receive ATT. The number of patients treated with warfarin and DOAC in the hospital increased to 14.8 % and 70.6 % (rivaroxaban, 33.4 %; apixaban, 25.5 %, and dabigatran, 11.7 %), respectively. The number of patients taking antiplatelet drugs decreased to 3.7 %, and the number of patients without ATT decreased to 10.9 %. There were no statistically significant differences in glomerular filtration rate (GFR) between these three groups at baseline. Only in the warfarin treatment group, GFR was significantly decreased from baseline during the follow-up period. Comparison of GFR in three study groups at the finale stage of the study showed significant differences between mean GFRs in the warfarin treatment group and the DOAC treatment group and between the warfarin treatment group and the ASA treatment group.Conclusion Among the prescribed and taken anticoagulants, DOACs are presently in the first place. Among DOACs, the most frequently prescribed drug is rivaroxaban. GFR decreases with the DOAC treatment slower than with the warfarin treatment. Despite the slower decrease in GFR with the ASA treatment compared to warfarin, ASA is not indicated for prevention of stroke in AF due to its low efficacy.

ABSTRACT

The study of the whole range of measures of primary dentofacial anomalies prevention has determined the most often used methods of their prophylaxis. It is also shown that consultations with specialists in the allied medical areas and use of technical preventive devices are underestimated. Information modalities for patients, hygiene (sanitary) education are not at due level. Small attention was paid to preventive examinations of children in the so-called organized collectives and to regular medical check-up of children population.

ABSTRACT

Children with cardiovascular dysfunction on sanatorium treatment underwent adaptation which proceeds without pathological shifts and depends on initial functional status of a child. Readaptation was associated with more serious alterations. Critical periods of an unfavorable course of adaptation and readaptation are described. Corrective measures are considered with respect to cardiovascular, autonomous nervous and psychoemotional statuses.

ABSTRACT

Cytogenetical investigation of 50 diagnostic chorionic villus samples from women with a high risk of giving birth to babies with chromosomal and genic pathology, and of 128 chorionic samples obtained from medical abortions, both on the 8-12th weeks of gestation was performed by means of original direct chromosomal analysis. Chromosomal anomalies were found in 6 cases of diagnostic chorion biopsies (12%) and in 4 cases (3%) of medical abortions. The former group included 5 embryos with autosomal trisomy (4--Ts21 and 1--Ts13) and one embryo with monosomy 18. The latter group contained 2 embryos with X-chromosome monosomy and 2 other with chromosomal mosaicism. A significant prevalence of the female sex was found in the diagnostic group (sex ratio 0.56), but not in the medical abortion one (sex ratio 1.0). Analysis of routine chromosomal preparations and those after in situ hybridization with X-chromosome alfoid-probe YAP 1-10 revealed polyploidy in average in 0.8-1% chorion cells. The feasible causes of sex ratio distortion in embryos of diagnostic group and factors responsible for the rate of polyploidy are discussed. High reliability of originally elaborated direct "shaking-blotting" method of chromosomal preparations from chorionic villus samples is stressed.
